Optical Photometry of Type II-P Supernova 2004dj in NGC 2403

Tianmeng Zhang, Xiaofeng Wang, Weidong Li +4

We present photometric data of the type II-P supernova (SN) 2004dj in NGC 2403. The multicolor light curves cover the SN from 60 to 200 days after explosion, and are measure…

Spectral Energy Distributions of M81 Globular Clusters in BATC Multicolor Survey

Jun Ma, Xu Zhou, David Burstein +4

In this paper, we give the spectral energy distributions of 42 M81 globular clusters in 13 intermediate-band filters from 4000 to 10000 A, using the CCD images of M81 observed as p…

037-B327 in M31: Luminous Globular Cluster or Core of a Former Dwarf Spheroidal Companion to M31?

Jun Ma, Sidney van den Bergh, Hong Wu +6

037-B327 is of interest because it is both the most luminous and the most highly reddened cluster known in M31. Deep observations with the Advanced Camera for Surveys on the Hubble…

Color and Metallicity Distributions of M81 Globular Clusters

Jun Ma, Xu Zhou, Jiansheng Chen +4

In this paper we present catalogs of photometric and spectroscopic data for M81 globular clusters (GCs). The catalogs include B- and V- photometric and reddening data of 95 GCs, an…
